From an essay by Emerson on manners:
"The chiefs of savage tribes have distinguished themselves in London and Paris, by the purity of their tournure. "
It is obviously of French origin, but the onlline French dictionaries did not have it. My dictionary and AHD did not have it. But ARTFL Webster 1913 gave :
ournure (Page: 1522)

Tour*nure" (?), n. [F., fr. tourner to turn.]

1. Turn; contour; figure.

2. Any device used by women to expand the skirt of a dress below the waist; a bustle.

But "figure" doesn't seem "le mot juste". "bearing" seems
closer, but I'm not satisfied with it. Let's hear some
suggestions, please.
